In this way'it will be per ceivedthat the water is exposed for,the long est period- .of time the eat,which b reason of the serpentine path in which the 1 eat is directed onaccount i of the staggered arran ement' of the coils 1, as herelnabove'descri ed, is brought. into close contact with both the bottom and the10.- This in the arrangement shown in Fig. 6

Inpractice I have foundthat a continuous stream of boiling water may bedrawn from the exitpipe 18. This makes the by water-tight joints intothe up or and lower s des of the 0011s 1, between W 'ch they arelocated, and serve to space said device practical and in the highestdegree satisfactory for the uses contemplated and set forth above. Thusis secured the greatest economy of fuel and also much uicker results inthe way of water heated to t e desired tem erature. I

.' T e pipes 15,16, and 17 are suitably fitted coils apart and also tosu port the upper ones u on the lower ones. t the end of the secon coil1, opposite thepipe 15, is located a standard 19 to support the secondcoil 1 at that end. A similar standard 20 is placed at the end of thethird coil op osite the pipe 16 and for a like purpose. T estandard 21su ports thehighest C01l 1 at the op osite end to similar manner, T elowest 00' 1 is pare tially supported by the inlet water-pipe14 and alsoy angle-irons 22,- only one of which is shown ln'Fig. 1, the otherbeingv attached that is roken away.

each burner consisting of three tubes 4 and each tube 4 being supphedwith a plurality of each ipe 17 in to said rows'of perforations 5 in itsupper arc and oup of three tubes being sup lied from an in et-pipe 26,to which a supp y-pipe 27 leads by suitable branches. Projecting fromsaid supply-pipe 27 is the branched pipe 28, leading to the igniter 29,,containing erfora tions 30. When the gas is admitte to the tubes 4 by 0ening the cooks 31 and a light is applied to t e igmter 29, the latterthrows a flame obliquely across the six tubes 4 formin the burners.

. it will be understood that many minor changes in the form andarrangement of the several parts of my invention may be made; butthechief feature thereof consists in the application 'of heat derived fromany source and introduced at a point adjacent and lpreferably below thelowest of a vertical co umn consisting of a plurality oftiers of watertubes or coils, said colls occupying a staggered relarelation to eachother.

Having thus described my said invention, what I claim, and desire tosecure by Letters Patent, is-
